There was no place in Scolari's Euro 2008 group for Chelsea's former on-loan midfielder Maniche, who now plays for Inter Milan. The 30-year-old's omission was the only surprise in the squad announcement.
Portugal finished as runners-up to Greece on home soil in 2004 and Scolari, who won the 2002 World Cup with Brazil, is expecting another strong performance.
"The expectations are the same as in 2004," added Scolari, who will step down as Portugal coach after the competition.
"We have great quality to clinch the qualification in the first phase. I have total belief in this squad."
Portugal are in Group A with the Czech Republic, Turkey and co-hosts Switzerland.
Defenders: Miguel Monteiro (Valencia), Jose Bosingwa (Porto, to join Chelsea after tournament), Paulo Ferreira (Chelsea), Ricardo Carvalho (Chelsea), Fernando Meira (VfB Stuttgart), Bruno Alves (Porto), Pepe (Real Madrid), Jorge Ribeiro (Boavista)
